The forelimb bones of a cat are ____________ to the forelimb bones of a bird. The wings of an insect are ____________ to the wings of a bird. The hindlimb bones of a whale are ____________ . (Options: emergent, adaptive, analogous, vestigal, homologous)
Homework Answers
The fore limb bones of cat are homologous to the forelimb bones of birds as they are structurally nearly identical. But function wise serve different.
The wings of insect and wings of birds are analogous. As they serve same functions with different structure.
The hindlimb of whale is vestigial. As the whale lives in ocean it serves no purpose for the whale to have hind limb.

Structures as different as horse hooves, bat wings, and whale flippers contain pentadactyl bones that develop from the same embryonic tissues. How have evolutionary biologists interpreted these similarities? a) By proposing that horses, bats, and whales share a common ancestor. b) By identifying the bones as being analogous structures. c) By applying the principle of convergent evolution. d) Two of the other statements are correct Please help

Bird bones have air pockets in them to reduce their weight. This also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 45.0 g and its apparent mass when submerged is 3.60 g(the bone is watertight). What mass of water is displaced? mass of water displaced: kg What is the volume of the bone? volume of the...

2) Many animal predators tend to preferentially eat familiar prey types. This behavior imposes ____________ on the prey species. positive frequency-dependent selection pleiotropy a heterozygote advantage negative frequency-dependent selection 3) Which of the following statements is true? Natural selection can create new phenotypes from scratch. Mutations occur in response to natural selection imposed by the environment. Gene flow and genetic drift are capable of working against natural selection. Organisms with very long generation times are likely to adapt easily. 4)...

1) A cat of mass 1kg leaps to try to catch a bird. If the cat's jump was at an angle of 60 degrees with an initial velocity of 3 m/s, it's vertical displacement at the highest point of its trajectory is: 2) Suppose another cat of mass 2kg make the jump with the same initial velocity (3 m/s at an angle of 60 degrees with the horizontal). The total time this heavier cat is in the air is: Please...
